Lenght of the line

[ludvigtyden]

Hi, the function "pandapower.create_line(net, from_bus, to_bus, length_km, std_type, name=None, index=None, geodata=None, df=1.0, parallel=1, in_service=True, max_loading_percent=nan, alpha=nan, temperature_degree_celsius=nan, **kwargs)" takes length_km as input. Is that the length of the actual conductor or is it the lenght of the span between towers? or are they equivalent i.e the line has no sag?
